Evaluation of synthetic wheat lines (Triticum durum/Aegilops tausсhii) for vegetative period and resistance to diseases

The growth of the total wheat production and increase of yield stability from year to year are some of the priorities of agriculture in Russia. The yield of commercial varieties significantly diversifies due to huge losses of their potential under the influence of negative biotic and abiotic factors. Increase of resistance to stress factors in the emerging varieties can be achieved by utilizing the diversity of the genetic resources of related wild species and genera in crosses. The results of a phenotypic evaluation of the synthetic hexaploid wheat lines of CIMMYT breeding created by crossing durum wheat varieties from Institute of Breeding and Genetics (Odessa, Ukraine) and variety Pandur from Romania (T. durum Desf., AB genome) with Aegilops (Ae. tausshii Coss., D genome), and also 15 synthetic wheat lines of Kyoto University breeding (Japan) created by crossing durum wheat variety Langdon with different ecological forms Aegilops are presented. Research was performed on the experimental field of Omsk SAU under conditions of southern forest-steppe of West Siberia in 2016. Between synthetics, there was revealed a genotypic difference in the vegetative period duration and resistance to diseases. Lines of hybrid combination Aisberg/Ae.sq.(511) were characterized as the most early-maturity genotypes among the lines studied. The hybrid combinations Ae.sq.(369) with variety Aisberg, Ae.sq.(310) and Ukr-Od 1530, Ae.sq.(223) and Pandur are characterized by complex resistance to fungal diseases. Most of the lines demonstrated high and moderate resistance to rust fungus, severity ranging from 5 to 70 % and severity of powdery mildew being 10–90 %. Lines derived from variety Ukr-Od 1530.94 and accessions Ae. tauschii (392); (629); (1027); (1031) and lines Langdon/Ku-2074; Langdon/Ku-2075; Langdon/Ku-2100; Langdon/Ku-2079 are characterized by complex resistance to powdery mildew, leaf and stem rust. The synthetic lines with a complex of economically valuable traits present interest as an initial material for breeding programs

Standardization of epiphenomenon risks by the use of identification of early symptoms of critical states of oncohematological children

In the article is reviewed increase of effectiveness and safety of treatment of children with oncohematological conditions, by the use of timely symptoms diagnostics of epiphenomenon, critical states progression, for correction of specific and symptomatic therapy. Elsewhere, for evaluating children’s condition the PEWS (Pediatric Early Warning Systems) scale is being used, but for adequate evaluation of oncohematology children’s conditions this scale was not credible enough. The track record of observation on patients at resuscitation and intensive care unit for oncohematology children (RICU OH), has educed significant criteria for modernization of the PEWS scale. Including to it presence of various hemorrhagic syndrome, statistical frequency of transfusion and hematological parameters. The result of research shown the necessity of implementing to the scale additional criteria, and using of it at clinical recommendationsВ статье рассмотрено повышение эффективности и безопасности лечения детей с онкогематологическими заболеваниями, путем своевременной диагностики предвестников риска развития осложнений, критических состоянии, для коррекции специфической и симптоматической терапии. За рубежом для оценки состояния у детей используется шкала PEWS (Pediatric Early Warning Systems), но для адекватной оценки состояния онкогематологических детей данная шкала была недостаточно достоверна. Опыт наблюдения за пациентами в отделении реанимации и интенсивной терапии для онкогематологических детей (ОРИТ ОГ), выявил значимые критерии для модернизации шкалы «PEWS». Включив в нее наличие различного геморрагического синдрома, частоту трансфузии и показатели крови. Результат исследования показал о необходимости внедрения в шкалу дополнительных критерии, и использования его в клинических рекомендация

Genotypic and ecological variability of zinc content in the grain of spring bread wheat varieties in the international nursery KASIB

Spring bread wheat is the staple crop in Western Siberia and Kazakhstan, a significant portion of which goes for export. Wheat breeding with a high level of zinc in wheat grain is the most cost-effective and environmentally friendly way to address zinc de iciency in the diet. The purpose of this work was to evaluate the contribution of the factors ‘location’ and ‘genotype’ in the variability of zinc content in wheat grain, and to identify the best varieties as sources of this trait for breed-ing. The research on screening zinc content in the wheat grain of 49 spring bread wheat varieties from the Kazakhstan-Siberia Spring Wheat Trial (KASIB) nursery was carried out at 4 sites in Russia (Chelyabinsk, Omsk, Tyumen, Novosibirsk) and 2 sites in Kazakhstan (Karabalyk and Shortandy) in 2017–2018. The content of zinc in wheat grain was evaluated at the Ionomic Facility of University of Nottingham in the framework of the EU pro ject European Plant Phenotyping Network-2020. The analysis of variance showed that the main contribution into the general phenotypic variation of the studied trait, 38.7 %, was made by the factor ‘location’ due to different contents of zinc and moisture in the soil of trial sites; the effect of the factor ‘year’ was 13.5 %, and the effect of the factor ‘genotype’ was 8.0 %. The most favorable environmental conditions for accumulation of zinc in wheat grain were observed in the Omsk region. In Omsk, the average zinc content in all studied varieties was 50.4 mg/kg, with 63.7 mg/ kg in the best variety ‘OmGAU 100’. These values are higher than the target values of the international program Harvest Plus. ‘Novosibirskaya 16’ (49.4 mg/kg), ‘Silach’ (48.4 mg/kg), ‘Line 4-10-16’ (47.2 mg/ kg), ‘Element 22’ (46.3 mg/kg) and ‘Lutescens 248/01’ (46.0 mg/kg) were identi ied as being the best varieties. Significant possibilities for the production of wheat grain with high zinc content, which is in demand for the production of bread and pastry products with functional properties, were identified in the Western Siberian region

The Probabilistic Measures Approximation of a Resource Queuing System with Signals

Modern wireless networks are characterized by high user mobility. This factor can lead to changes in the quality of the channel during the lifetime of the interaction session. To take into account the fact of user movement in a resource queuing system with signals are introduced. Signal arrivals trigger resource reallocation of customers in the system. In this paper, we introduce an approximate model that replaces the flow of resource reallocations with the additional flow of customers. The convergence of the approximate iterative evaluation method is proved. Besides, we provide a case study for the accuracy assessment of the approximate method. © 2021, Springer Nature Switzerland AG
